The next step are constant references. We recall that a reference is an alias for a variable. If we add constness to it, we annotate, that the aliased variable may not be changed through this handle: Run this code #include <iostream> int main() { int x = 0; const int y = 1; ...
inty=0;constinta=std::is_constant_evaluated()?y:1;// 试探性常量求值失败。放弃常量求值。// 变量 a 被动态初始化为 1constintb=std::is_constant_evaluated()?2:y;// 以 std::is_constant_evaluation() == true 进行的常量求值成功。// 变量 b 被静态初始化为 2 ...

1) 概念constant_range 是概念 range 的精化。对于满足它的范围,ranges::begin 返回常量迭代器。2) 当输入迭代器的间接操作结果是其常引用(隐含只读)时,概念 /*constant-iterator*/<T> 得到满足。示例运行此代码 #include <ranges> #include #include <string_view> #include <vector> // 确保参数为常量范...

You can write multibyte characters in C source text as part of a comment, a character constant, a string literal, or a filename in anincludedirective. How such characters print is implementation defined. Each sequence of multibyte characters that you write must begin and end in the initial sh...
Description This function sets one configuration parameter with the specified configuration value and throws anstd::runtime_exceptionin the case that it fails. Each configuration parameter is a named constant, and the configuration value must have the corresponding type, which can be a named constant...
